To all whom, it may concern:

' Be it. known that l, STEWART H. Jones, a citizen of the United States,residing at Buffalo, in the county of Erie, State of New York, haveinvented certain new and useful Improvements in Journal-Bearings, of

which I do declare the following to be a full, clear, and exertdescription, reference being had to the aeeompanying drawings, formingpart of this specification.

The present invention has relation to that plates of journal hearings(-onunonly lcnown as composite hear ings,.iu which the wearing portionof the bearingis' formed of bronze, brass or similar material, rhinforced by a hack of iron, steel or like cheap, strong and durableineial.I

In composite journal hearings of the eharacter desorihed, as heretoforeconstructed, it has been customary toextend the iron or steel liael:downward to the lower side edges of the bearing and to form upon suchiron back. the flanges and lugs that serve to position the bearingwiihin the journal box. This construetion of hearing has been found ohjetionahle for the reason that after oonsiderahle wear the iron back isapt to COiIlP in contact with the journal, thereby causing overheatingand injury of the parts.

One of the main objects of the present invention is to provide aCOlllpOSltQ journal bearing in which the sidii: flanges and lugs areformed integral with the biioly portion or bearing of brass, while thereinforcing shell of iron or steel partially encircles the brass, butterminates at a point inside the flanges and lugs.

The invention eonsists in the features of novelty hereinafterdescribed,illustrated in the a'iteompany i ng drawing and particularly pointed outin the claims at the end of this specification.

Figure 1 loan end view of a composite journal been ing embodying myinvention. Fig. 2 is a iew in vertical cross sectionon line 2-2 of Figs.and 4. 1* lg. 3 is a view in longitudinal section on line 5 ---3 of Fig.2. Fig. 4 is a plan View of my lEllPIOVBd hearing.

A designates the body portion of the bearing that is formed of brassbronze or similar metal and B denotes the upper shell or back portionthat will be formed: of cast iron, steel or like cheap, strong anddurable metal. Integral with the body portion A are formed the usualside flanges a and lugs a common to journal hearings of the Master (JarBuilders type. At the ends of the body portion of the hearing are alsoformed the upwardly extending flanges a and a between which rests theiron shell 13. The upper face of the body portion A of the hearing isformed of polygonal outline and the inner face of the shell B isoorrespondupon the vertical flanges 11 and a? at the ends of the bod}portion A, one of these notches b being. formed in the vertieal flangeatfone end of the ironshell B. By reference to Figs. 1', 2 and l of thedrawings, it will be seen that thejiower edges b" of the downwardlyextending side walls o of the shellll terminate above and inside theflanges u and lugs 1:. of the body portion A. The iron hat-k or shell l3and the body portion or brass inny be ('aSt' separately and then settogether lor use, the shell being securely interlocked with the bodyportion or brass by the end flanges a" and a, end lugs o" and by theengagement of the side wells 15 of the shellwith the correspondinglyinclined upper side parts o f the body portion A My'invemion affords amost durable and safe constructi n of hearing, possessing the goodqualities of an alhhrass bearing and having also the increased strength,cheapness and durability of the iron-bank beariny'. inasmuch as the sidewalls of the'iroh-haclt terminate above and inside the flanges and logse and a that are,v

formed integral with he hodv'portion A, .all danger of the iron shell orllllt'li (tuning in contact with the journal, alter long serviee, isavoided, and thevertical flanges a and a at the ends of the body portionA also serve to effectively prevent eontat-t of the ends of the ironback with the journal. The iron back or shell B can bereappiied to newbody portions A, whenever the latter have bBCfilItQ EO worn as'to unlitthem for further use.

Having thus described Illy lHVllGtlDIl, what i claim as new, and desireto secure by Letters Patent, isz- 1. A journal hearing coninris g a bodyportion of brass flangesformed lnt'e rnl'therewith and an lron'shellextendln iii-rose and partially down the sides of said body p01- rien.said shell oetng of proper thickness, size and shape to extend hetweenthe 0nd flanges and to terminate at the rial it rln vertical endflanges. and side side flanges thereof. said side flanges projectinglaterully/ heyo'nd said shell. v

2. A journal hearing comprising a body portion of brass or liltojtl"rial having lnrlned integral therewith vertical end Ganges and lateralside flanges and lugs and an iron shell extending across the top ol saidbody portion and interlocked at its ends with the vertical end flangesof said body portion. said iron shell terminating inside the llne of theside flanges and lugs of said body portion.
